Orital Plug Valve

When the valve is tuly ooened,the chaonelot olug is in algnment wth the chaonelotvalve body, which can ensure ideal and owestdecrease on oressureWhen the hand wheelis turned, the plug wilrotate toward the closing direction, and at the same time drafthe rotation of valve disc by 90 degree, whenthe hand wheelis lured furheron, the plug wilbe pressed down, and make the valve disc open to lwo sides, so thatthe valve disc wilbe in firm conlaciwith the valve seat and close the valveWhen the hand wheel is turned inversely, first of all the plug wil move upward, and the valve disc and valve seat wil be separated: if the hand wheel istured further on, tilthe valve disc is truned by 90 degree driven by the plug, and finally the channel of plug wil be in alignment with the channel of valvebody,so that the valve is be fully opened.

The track-mounted plug valve (General Valve) is designed according to standards such as API 6D, API 599, and GB/T 22130. The sealing surface and plug adopt a guide rail structure. During valve opening, the plug is first lifted to a certain height via a transmission mechanism, and the two sliders follow closely, disengaging from the sealing surface. Then, the transmission mechanism rotates the plug and sliders together to the open position. During valve opening and closing, the valve disc separates from the valve seat, thus eliminating wear on the sealing surface. It is mainly used in metering systems and branch-pipe mixed-transmission systems in airport oil depots and refined oil depots, as well as in the storage and transportation of aviation fuel.
